Using different namespaces in ALUI remote portlets

Question

I'm trying to incorporate AJAX technology into our ALUI remote portlets. I'm using Backbase tools to try to do this. However, these Backbase tools have their own namespace defined for their custom tags. When I try to access the remote portlet, I get 'unrecognized namespace prefix' errors in PTSpy. Is there something special I need to do to get ALUI to recognize different namespaces? I have the following line in my remote portlet:
<pt:namespace pt:token="$PORTLET_ID$" xmlns:pt="http://www.plumtree.com/xmlschemas/ptui/" />
Do I need to do something with this line to use different namespaces?

Answer 1

I was able to get basic Backbase functionality running inside of ALUI. Since Backbase is booted from the onload method of the body tag, I had to create a Javascript method and call window.onLoad on that method to get Backbase to boot (it wouldn't recognize the onload method in my remote portlet).
Also, since I'm using remote portlets, I had to gateway the calls to Backbase using the Remote Portlet's Web Service settings.
In case anyone is interested, my remote portlet looks like this (where the server listening on port 7001 is the gateway server, and the server listening on port 7021 is the server running Backbase):
<%@ page language="java" contentType="text/html;charset=UTF-8"%>
<pt:namespace pt:token="$$PORTLET_ID$$" xmlns:pt="http://www.plumtree.com/xmlschemas/ptui/" />
<style type="text/css"> #pt-portlet-$$PORTLET_ID$$ {border: solid 0px;}</style>
<script type="text/javascript" src="http://localhost:7001/portal/server.pt/gateway/PTARGS_0_0_299_209_0_43/http%3B/localhost%3B7021/Backbase/3_1_6/bpc/boot.js"></script>
<script language="javascript">
function runBPC()
          bpc.boot("<pt:url pt:href='http://localhost:7021/Backbase/3_1_6' xmlns:pt='http://www.plumtree.com/xmlschemas/ptui/'/>");
window.onload=runBPC;
</script>
<div
xmlns:b="http://www.backbase.com/b"
xmlns:s="http://www.backbase.com/s"
>
          <xmp b:backbase="true">
          <b:button>test</b:button>
          </xmp>
</div>
